Question:
I am interested in manufacturing self lubricating bearings. What would be the initial capital cost for such project? Would it be beneficial to use MIM as compared to powder pressing?

Question:
Sandvik, UK, produce Nitronic 60 (Fe - 17 Cr, 8 Ni, 8 Mn, 0.1 N2) for MIM application. Someone somewhere must be sintering this powder under vacuum. If we sintered such a high Mn powder ~3*10^-1 bar ~1190 °C, would there be any Mn loss? Mn seems to a have a high vapor pressure.

Question:
I understand diamond tools for cutting different type of stones can also be produced through MIM process?

Question:
I am in the business of plastic compounding. I want to diversify in to metal powder compounding.
1)Is compounding equipment the same as for plastic compounding?
2)Which are most commonly used compounds in MIM industry, in terms of quantity?
3)Which binder systems are most advisable in terms of environmental friendliness, economical processability during compounding, injection, de-binding and sintering?
4)Name and addresses of Water based, polymer based and wax based binder suppliers suitable for MIM compound?

Question:
I am doing research on MIM. I would like to ask you regarding the cost of setting up a small MIM facility in a developing country like India.
Roughly, how much does a MIM machine cost along with a sintering furnace and a batch mixer?
Thank You.

Question:
I wish to enter into the field of soft magnetic powder manufacturing and seek your advice. Thank you.

Question:
Are you aware of any publications or literature that describe industrial circuits that can produce electrolytic iron? It was a common practice in the first half of the 20th century but as such have had difficulty locating information on the subject.

Question:
I seek information on prior art and fields of application associated with the conveying of metal powders, specifically aluminium metal powders. My interest is with the mechanisms used rather than the fluid media employed to convey the particles but as much information on the subject would be appreciated...

Question:
I want to know the colour of copper powder. Is it light green in colour?

Question:
Can you tell me what copper powder PMU 99.999% purity is used for?
Also, what does PMU stand for?

Question:
How can you improve the relative density after sintering in pure copper powder metal injection moulding process?
I would also like to know the d50 of the metal powder for MIM.

Question:
Can electrolytic iron powder be used for MIM. Are there any technologies that can be used to make it spherical?

Question:
I have one question regarding powder-metal products, its complexity to press, sinter and bringing it into final shape according to different specifications. Can you evaluate if MIM can substitute the before mentioned process? I have some market indications which tell me a new technology will and maybe can substitute the pressing/sintering/machining process.I would like to know your expertise.

Question:
There has been a lot of talk on powder metal injection moulding of titanium but there seems to be very few parts being produced by this technology.  Why?

Question:
I wish to enter into the field of Iron powder manufacturing and seek your advise for the best possible manufacturing process.
What would be the reduction process of sponge iron?

Question:
We are looking for various powders for the welding industry. Do you have an insight into the welding industry and where we might be able to find potential reliable sources for our requirements?

Question:
I’m a PhD student in Malaysia, I would like to do research in “Material Processing – Development of Micro part using Metal Injection Moulding Process”.  I would like to know new subjects in this field for research in the world.  Your guidance will be appreciated.
